O Macmillan Learning Industrial processes often require the damping of vibrations. Consider a workbench that uses four large ideal springs in place of traditional legs, with each spring supporting one corner of the workbench and exhibiting a force constant of k = 47500 N/m. This workbench is used when creating products that involve highly unstable chemicals. According to specifications, the acceleration of the manufacturing equipment must be held to less than 21.6 m/s² for the manufacturing process to proceed safely. The amplitudes of vibrations are expected to remain under 0.592 mm throughout. Given that the workbench and maufacturing equipment have a combined mass of m= 5.95 kg, find the maximum acceleration amax expected of the equipment and workbench. Ignore the mass of the springs. Omax = Does the workbench meet the specifications for acceleration? yes no m/s² An engineer decides to damp the oscillations by applying one shock absorber to each spring. These shock absorbers apply a that oppores the motion of the bench. For proper damping, the engineer decides that the F
Simple harmonic motion
Simple harmonic motion is a type of periodic motion in which an object undergoes oscillatory motion. The restoring force exerted by the object exhibiting SHM is proportional to the displacement from the equilibrium position. The force is directed towards the mean position. We see many examples of SHM around us, common ones are the motion of a pendulum, spring and vibration of strings in musical instruments, and so on.
Simple Pendulum
A simple pendulum comprises a heavy mass (called bob) attached to one end of the weightless and flexible string.
Oscillation
In Physics, oscillation means a repetitive motion that happens in a variation with respect to time. There is usually a central value, where the object would be at rest. Additionally, there are two or more positions between which the repetitive motion takes place. In mathematics, oscillations can also be described as vibrations. The most common examples of oscillation that is seen in daily lives include the alternating current (AC) or the motion of a moving pendulum.
